Answer:
B. 40, 51.5, 88.5
Step-by-step explanation:
(5x - 4) + (2x + 3) + (3x- 4) = 180
10x - 5 = 180
10x = 185
x= 18.5
Substitute
5(18.5) - 4 = 88.5
2(18.5) + 3 = 40
3(18.5) - 4 = 51.5
3/2+3/2=3 That is a good equation because all of the characters are bigger than one 3/2 is equal to 1.5 and 3 is greater than 1
Answer: FG = 3x + 10
<u>Step-by-step explanation:</u>
EF + FG = EG <em>Segment Addition Postulate</em>
x-7 + FG = 4x+3 <em>Substitution</em>
-7 + FG = 3x + 3 <em>Subtraction Property of Equality</em>
FG = 3x + 10 <em>Addition Property of Equality</em>
The dependent Variable would be
D. 4

Given,
Now, we have to find f (-5). To find this, we just need to substitute -5 in the place of x.
So,
